The I2C adapters on Freescale MPC107/824x/85xx/512x/52xx/83xx/86xx all
have the same name "MPC adapter". Since I2C adapter numbers can change
across reboots and even after loading/unloading an I2C bus master driver,
adapter names have to be used to identify adapters and thus should be
unique and well defined. Since this is not the case with this driver,
it is difficult if not impossible to identify a specific adapter from
user space on affected platforms.

To remedy the problem, use the adapter memory address as part of the
adapter name.

With this patch, adapter names are:
On P2020:
MPC adapter at 0xfff703000
MPC adapter at 0xfff703100

On P5040:
MPC adapter at 0xffe118000
MPC adapter at 0xffe118100
MPC adapter at 0xffe119000

To enter high speed mode, following steps should be done:
1. When running in high speed mode, i2c clock rate is different
from standard mode. Clock rate must be set according to
specification first.
2. When i2c controller sends a master code and wins arbitration,
high speed mode is entered.

If you want to enable high speed mode, the following members of
platform data should be set to proper value:
1. "high_mode" should be set to "1".
2. "master_code" should be set to "8'b 0000_1xxx"(x is 0 or 1).
   If no master_code is set, set to default value 0xe.
3. "rate" should be set according to specification.

This doesn't show up unless you do quite a bit of testing; a simple

The reason for this is that install_special_mapping() expects the

NetLabel has the ability to selectively assign network security labels
to outbound traffic based on either the LSM's "domain" (different for
each LSM), the network destination, or a combination of both.  Depending
on the type of traffic, local or forwarded, and the type of traffic
selector, domain or address based, different hooks are used to label the
traffic; the goal being minimal overhead.

Unfortunately, there is a bug such that a system using NetLabel domain
based traffic selectors does not correctly label outbound local traffic
that is not assigned to a socket.  The issue is that in these cases
the associated NetLabel hook only looks at the address based selectors
and not the domain based selectors.  This patch corrects this by
checking both the domain and address based selectors so that the correct
labeling is applied, regardless of the configuration type.

In order to acomplish this fix, this patch also simplifies some of the
NetLabel domainhash structures to use a more common outbound traffic
mapping type: struct netlbl_dommap_def.  This simplifies some of the code
in this patch and paves the way for further simplifications in the
future.

It's possible to assign an invalid value to the net.core.somaxconn
sysctl variable, because there is no checks at all.

The sk_max_ack_backlog field of the sock structure is defined as
unsigned short. Therefore, the backlog argument in inet_listen()
shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall
is truncated to the somaxconn value. So, the somaxconn value shouldn't
exceed 65535 (USHRT_MAX).
Also, negative values of somaxconn are meaningless.

before:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536
net.core.somaxconn = 65536
$ sysctl -w net.core.somaxconn=-100
net.core.somaxconn = -100

after:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536

[  198.720740] eth0: Transmit timeout, status 00000204 00000000

timer routine checks the link status and if it's up calls
netif_carrier_on() allowing upper layer to start the tx queue
even if the auto-negotiation process is not finished.

Also remove ugly auto-negotiation check from the sis900_start_xmit()
